</span></span> * @class Ext.Panel
 * @extends Ext.Container
 * &lt;p&gt;Panel is a container that has specific functionality and structural components that make
 * it the perfect building block for application-oriented user interfaces.&lt;/p&gt;
 * &lt;p&gt;Panels are, by virtue of their inheritance from {@link Ext.Container}, capable
 * of being configured with a {@link Ext.Container#layout layout}, and containing child Components.&lt;/p&gt;
 * &lt;p&gt;When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.Container#add adding} Components
 * to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether
 * those child elements need to be sized using one of Ext's built-in &lt;code&gt;&lt;b&gt;{@link Ext.Container#layout layout}&lt;/b&gt;&lt;/code&gt; schemes. By
 * default, Panels use the {@link Ext.layout.ContainerLayout ContainerLayout} scheme. This simply renders
 * child components, appending them one after the other inside the Container, and &lt;b&gt;does not apply any sizing&lt;/b&gt;
 * at all.&lt;/p&gt;
 * &lt;p&gt;A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate
 * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional
 * information).&lt;/p&gt;
 * &lt;p&gt;Panel also provides built-in {@link #collapsible expandable and collapsible behavior}, along with
 * a variety of {@link #tools prebuilt tool buttons} that can be wired up to provide other customized
 * behavior.  Panels can be easily dropped into any {@link Ext.Container Container} or layout, and the
 * layout and rendering pipeline is {@link Ext.Container#add completely managed by the framework}.&lt;/p&gt;
